Design of gearing between transmission and alternator for drive of the superstructure of the heavy truck
Charouz, Ondřej ; Nohál, Libor (referee) ; Košťál, David (advisor)
This Bachelor´s Thesis presents an engineering design of gearing between transmis-sion and alternator for drive of the superstructure of the heavy truck. The gear ratio from engine to the output of transmission is 0,432 for normal constant meshing or 0,538 for reduced constant meshing. The performance of truck is 270 kW at 1800 rpm and torque 1850 N.m at 1000 +200 rpm. The thesis is focused on engineering design of location change of dynamo and not only to reduce the possibility of collisions between the chassis and the V-belt but also to make the whole construction simpler.

Claw-pole automotive alternator design.
Szekeres, Vojtech ; Mach, Martin (referee) ; Hájek, Vítězslav (advisor)
The thesis deals with the alternators used in passenger cars, their desing, function and typical behaviours and characteristics and design. Alternators are specific with the trapezoidal shape of rotor poles, which produce a waveform similar to a square wave instead of a sinusoid. This is more desirable for simple rectification to direct current, which is used in the electrical distribution system of automobiles. Because of the shape of the poles, these alternators are also called the claw-pole. The design itself consists of creating an alternator in Ansys Maxwell software in compliance with real measured alternator. The results are compared numerically and also graphically.

Accumulator Charger for Bicycle
Kufa, Jan ; Kubíček, Michal (referee) ; Šebesta, Jiří (advisor)
The aim of this thesis is to suggest a suitable way of charging mobile devices by using bicycle. In the first part of bachelor thesis there are discussed various options for charging the battery on a bicycle, described differences between the alternator and dynamo, and finally the different types of batteries. The second part describes in detail used blocks that were used in the engagement and the reasons of their choice. In the last section there are described the final parameters of the charger.

Increase the Rated Voltage of the Vehicle's Circuit - Study
Škrla, Milan ; Vítek, Ondřej (referee) ; Hájek, Vítězslav (advisor)
Baccalaureate work themed Study voltage boost seat power control nets motor vehicles is document analysing actual fulfilment seat power control nets motor vehicles. S consideration on historical evolution, actual form and possible to dissemination seat power control nets are in work rectified conditions and groundwork for possibility heighten voltage rating. Size input appliances for purposes baccalaureate work were to be timed on motor - car lower middle class. Record from metering served for theoretic proposal source text system intended for increased surface explicit tension plumbed vehicles.
